Gasoline

Vedclass · Answer

(C) The boiling point of petroleum fractions depends on the number of carbon atoms in the hydrocarbon chains. Lower molecular weight hydrocarbons have lower boiling points. Gasoline (petrol) consists of hydrocarbons with $C_5$ to $C_{12}$ carbon atoms. Kerosene consists of $C_{12}$ to $C_{16}$,Diesel oil consists of $C_{15}$ to $C_{18}$,and Heavy oil consists of $C_{20}$ and above. Since Gasoline has the shortest carbon chain length among the given options,it has the lowest boiling point.
